LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented May 1, 1906.

To all whom it may concern:

Be it known that I, FREDERICK EGGE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Loose-Leaf Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to loose-leaf binders; and it consists in certain novel arrangements ofparts and combinations of parts hereinafter fully described and then particularly pointed out in the concluding claim.

In the accompanying drawings, Figure 1 is a plan view of my improved binder; Fig. 2, a rear view with the binding-clips closed Fig. 3, a view similar to Fig. 2, except that the binding-clips are open; Fig. 4, a section at the line as a: of Fig. 2, and Fig. 5 a section at the line y y of Fig. 3.

Similar numbers of reference denote like parts in the several figures of the drawings.

The casin 1 is preferably made of metal and is provided with depending sides 11 and 12 and depending ends 12. Each end is provided with a lateral extension or lug 12*. A wire rod 2 is positioned between the depending sides and ends of the casing and is journaled in depending housings 1. Each of these housings is formed by cutting or lancing the casing and folding the cut portion. The ends of the rod 2 are formed into arched or curved arms 3. An intermediate curved or arched arm 5 is fixed to the rod or shaft 2. Each of the curved or arched arms 3 and 5 extends through a depending side of the casing, which is also true of the stationary arched or curved arms 9, which arms are secured within the casing. The arms 9 are each provided with a right-angled extension 9*, which is secured parallel to the side 12 within the casing 1.

The depending housings 6 are formed between the depending sides 11 and 12 of the casing by lancing or cutting the top or horizontal portion of the casing 1. Straight wire springs 6 are fixedly secured within the housings 6. It will be noted that these housings 6 are located conti none to the centralportion of the casing. he outer free ends of the straight wire springs 6 are provided with collarsor rollers 8, which rollers engage beveled lugs 7', secured to the rod 2 near its ends and contiguous to the arms 3. It is obvious that the wire springs 6 constitute a spindle, upon which the rollers 8 revolve. Wire springs obviate the necessity of milling or specially preparing the same for the rollers 8. Each lug is beveled for facilitating. the adjustment of the arms against the action of the springs 6. Each lug is provided with a reduced extension or stem 7, Figs. 4 and 5, which stem is fitted into an aperture formed in the rod or shaft 2. When the arms 3 and 5, carried by the rod or shaft 2, are thrown outwardly or upwardly, the springs 6 will readily yield and will exert suflicient pressure against the beveled lugs 7 so as to hold the rod 2 against accidental turning. When the arms 3 and 5 are thrown inwardly, they will meet the arms 9, and thereby form closed loops, as shown in Figs. 1 and 4, and when arms 3 and 5 are thrown outwardly these loops will be open, as shown in Fig. 5.

The casing 1 is preferably cut away at the base of all of the arms, as shown at 10, so that no part of the arms or the rod 2 extend beyond the sides 11 and 12 and ends of the casing 1. One of the chief objects of my improvement is to confine the parts within as small space as possible, so that the casing and parts contained therein may occupy a minimum space at the back of the usual cover, within which devices of this character are utilized. The right-angled or base extensions 9 of the arms 9, as well as the rods 2, are positioned parallel and contiguous to the depending sides of the casing 1. By extending the arms through part of the casing a very compact device is formed. The extension 12 may be employed for engaging or to be engaged by suitable fastening means for attaching the device to a cover or suport.

What I claim as new, and desire to secure by Letters Patent, is

A device of the class described comprising an elongated strip having its edges bent to form parallel flanges along opposlte sides, a rod mounted beneath the strip and against one flange and arranged to be moved rotatably, arms carried by the rod and curved to The straight terminate above the strip, a resilient detent secured to the under side of the strip in parallelism with and adjacent to the rod, a lug carried by the rod in contact With the detent and positioned to contact With the under side of the strip to limit the rotary movement of the rod, and other arms secured in contact with the flange at the opposite edge and bent to meet the first-mentioned arm above the strip.

In testimony whereof I- affix my signature in presence of tWo Witnesses.
